It is C3 plant that can't shade tolerance. So it has to be planted on sunny fields.

The enzyme is also ubiquitous in C3 plant tissues, although a precise non-photosynthetic C3 function(s) is yet to be validated, owing largely to its low abundance in most C3 organs.

It is generally accepted that the carbon isotopic composition of plant material is correlated with C3 and C4 pathways of carbon fixation in photosynthesis.
